Looking for UltraDyne cam specs

Post by Ron Miller »

I'm looking for cam details-specs for a old UltraDyne roller cam for a small block chevy. See attached pictures for numbers stamped on the end of the cam.

Pic is blurry.

304/310 duration. R6. 106 LSA

could be roller cam master lobes R18. and R20

Go to the Bullet/Ultradyne cam lobe master list on their site and find these.

I have an UltraDyne cam with a lot of circle track stuff I bought last year. It's a nice cam but it's on a 102° and I am not sure how well that's going to work in a bigger inch drag engine.
